Quantitative Phase Imaging with a Meta-Based Interferometric System

ACS Applied Materials & Interfaces, Год журнала: 2025, Номер unknown

Опубликована: Апрель 15, 2025

Optical phase imaging has become a pivotal tool in biomedical research, enabling label-free visualization of transparent specimens. Traditional optical techniques, such as Zernike contrast and differential interference microscopy, fall short providing quantitative information. Digital holographic microscopy (DHM) addresses this limitation by offering precise measurements; however, off-axis configurations, particularly Mach-Zehnder Michelson-based setups, are often hindered environmental susceptibility bulky components due to their separate reference object beam paths. In work, we have developed meta-based interferometric system using common-path DHM configuration. A meta-biprism, featuring two opposite gradient phases created GaN nanopillars selected for low loss durability, serves compact efficient splitter. Our effectively captures the complex wavefronts samples, retrieval information, which demonstrate standard resolution targets human lung cell lines. Additionally, our exhibits enhanced temporal stability compared conventional reducing fluctuations over extended measurement periods. These results not only underline potential metasurfaces advancing capabilities but also promise significant advancements diagnostics.

Achromatic Full Stokes Polarimetry Metasurface for Full-Color Polarization Imaging in the Visible Range

Nano Letters, Год журнала: 2024, Номер unknown

Опубликована: Окт. 3, 2024

Metasurfaces provide an ultrathin platform for compact, real-time polarimetry. However, their applications in polychromatic scenes are restricted by narrow operating bandwidths that causes spectral information loss. Here, we demonstrate full-color polarization imaging using achromatic polarimeter consisting of four polarization-dependent metalenses. Leveraging intelligent design scheme, achieve effective arbitrary phase compensation and multiobjective matching with a limited database. This system provides broadband achromaticity across wavelengths from 450 to 650 nm, resulting relative bandwidth approximately 0.364 full Stokes imaging. Experimental reconstruction errors 450, 550, nm 7.5%, 5.9%, 3.8%, respectively. Performance is evaluated based on both crosstalk, our achieving three times the performance current state-of-the-art. The full-color, full-polarization capability device further validated customized object. proposed scheme advances practical applications.
